Google full text of this book:

Since Einstein first described them nearly a century ago, gravitational waves have been the subject of more sustained controversy than perhaps any other phenomenon in physics. These as yet undetected fluctuations in the shape of space-time were first predicted by Einstein's general theory of relativity, but only now, at the dawn of the twenty-first century, are we on the brink of finally observing them.

Daniel Kennefick's landmark book takes readers through the theoretical controversies and thorny debates that raged around the subject of gravitational waves after the publication of Einstein's theory. The previously untold story of how we arrived at a settled theory of gravitational waves includes a stellar cast from the front ranks of twentieth-century physics, including Richard Feynman, Hermann Bondi, John Wheeler, Kip Thorne, and Einstein himself, who on two occasions avowed that gravitational waves do not exist, changing his mind both times.

The book derives its title from a famously skeptical comment made by Arthur Stanley Eddington in 1922--namely, that "gravitational waves propagate at the speed of thought." Kennefick uses the title metaphorically to contrast the individual brilliance of each of the physicists grappling with gravitational-wave theory against the frustratingly slow progression of the field as a whole.

Accessibly written and impeccably researched, this book sheds new light on the trials and conflicts that have led to the extraordinary position in which we find ourselves today--poised to bring the story of gravitational waves full circle by directly confirming their existence for the very first time.


"The great achievement of Daniel Kennefick's fascinating Traveling at the Speed of Thought is that he takes...assumed existence of gravitational waves apart. He is not out to show that they do not exist--far from it. Rather, he carefully explains how durable skepticism has been toward the existence of gravitational waves ever since Einstein first predicted them...Kennefick offers a readable account of the theory of gravitational waves, exploring why skepticism was a reasonable stance at various points in the 20th century and why it has ceased to be so in the 21st."--Michael D. Gordin, Science

"This dense account of the history of gravity waves--undetected ripples in space-time--is the kind one might think would appeal only to physicists. But Kennefick uses this narrow subject to elucidate the larger issue of metaphors and analogies in science. A practicing gravitational wave researcher, Kennefick keenly explains how scientists become willing to believe that which they cannot see, or even observe experimentally."--SEED Magazine

"In Traveling at the Speed of Thought, Daniel Kennefick gives an authoritative, insider's account of a scientific phenomenon that more of less everyone in the field believes to exist, yet no one has ever seen. This is a scholarly contribution to the history of twentieth-century provides a rare insight into the tension in physics between the abstract reality that emerges from mathematics, and the warm body of nature that we can see and touch."--Georgina Ferry, TLS

"Kennefick is the right author at the right time. He has strong connections to research in this area as well as being a historian and a very good storyteller...An impressive book, in that Kennefick thoroughly covers the material and still keeps it at a level that should be accessible to all readers."--E. Kincanon, Choice
